The heart of an amplifier is a source controlled by an input signal. A simplified model of a voltage amplifier is shown in Fig. 5-1(a). The input and output reference terminals are often connected together and form a common reference node. When the output terminal is open we have υ2 = kυ…Next Chapter >< Previous Chapter
